4 Claims.

This invention relates to strumming device In long chain beaming, thewarp in rope formis usually led from a source through tension rolls in atension frame andthen is led a substantial distance to a beamer where itis spread out into a fiat sheet by passing through a suitable comb orreed and then wound onto a warp beam for further processing, such as foruse in a loom for furnishing the warp to the loom and for other uses.

It very often happens that the warps are not properly separated andstick together, and by providing this strumming apparatus, the warps arestrummed ver much in the same manner as in a stringed instrument, suchas a banjo is strummed or played, so as to vibrate th warpthreads andseparate them from each other.

It is an object of this invention to provide means in a long chainbeaming apparatus or any type of apparatus wherein a warp sheet isplaced onto a warp beam for vibrating the warp threads and shaking themapart from each other.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, in which Figure 1 is a top plan view of aportion of beaming apparatus;

Figure 2 is an elevation of Figure 1 looking from the lower side ofFigure 1;

Figure 3 is an end elevation looking from the left-hand end of Figures 1and 2;

Figure 4 is an enlarged detailed View taken along the lines 44 in Figure1;

Figure 5 is an enlarged detailed view taken along the line 5-5 in Figure1 and showing the warp threads which have been omitted in Figure 1 atthis point.

Referring more specifically to the drawings, the numeral l indicates aportion of the frame of a beamer which .usually comprises uprights H andI2 having certain geared mechanism therein and, of course, the other endof the beam is suita'bly supported as only one side of the warper isshown. In this conventional beaming apparatus, there is a shaft M whichhas thereon a pinion l which is driven by any suitable means not shown.

Pinion l5 meshes with a pinion I6 mounted on a shaft l1 and also mountedon shaft I1 is a pinion 20, which pinion meshes with a pinion 2| havingintegral therewith a beveled gear portion 22 which meshes with a beveledgear 23, mounted on a shaft 24, which is suitably mounted in a bracket25, and upper end of this shaft has an arm 26 mountedthereon providedwith a pin 21 which is adapted to have movement in a slot 28 in n arm29, pivoted as at 39 on an angle bar 3| projecting from a rectangularframe which comprises not only the angle bar 3| but another bar 32 andend bars 33, only one of which is shown, there being another one at theother end of the frame. The rectangular frame comprising angle bars 3|,32 and 33, is supported by vertically disposed legs 34, having two ofthese legs at each end of the frame but only two of which re shown inthe drawing.

Pivotally mounted intermediate their ends as at 35 on bar 3| is apluralit of members 36, each of which has integral with one end, or eachend thereof a T-shaped portion 31 which has upwardly projecting ends forreceiving a bolt 38, which penetrates a hole in a member 40 to securethese members 40 in position. These members 40 are very thin andresilient and are such as is employed in a conventional electricaldropwire stop motion.

Pivotally secured, as at 42, to each of the members 36, is a bar 44which is pivotally connected as at 45 to the end nearest the observer inFigures 1 and 2 of the lever 29.

The warp 4|, before passing through a comb or reed 39, passes over thesemembers 36 and the strumming members 40 and is wound onto a conventionalwarp beam- 41 which is rotated in a conventional manner by the beamer.

It might be added that th invention which is mounted on the rectangularframe, comprising members 3 I, 32 and 33 and legs 34, is not attached tothe beam-er by any means except by the pin 21 engaging the slot 28 ofthe lever 29. The legs 34 support the strumming mechanism and it is slidinto position beneath the sheet of warp 48 and may be anchored to thefloor by any suitable means not shown, though its Weight would hold itin position.

In order to prevent the warp threads 4| from falling down onto thestrumming members 40, there is provided a pair of arms 49 which aresecured at one end to the bar 3|, only one of the bars 49 being shown,and these bars support a rod 50 a substantial distance above the bars 3|and 32, as well as the oscillating bar 44 because these bars might haverough edges thereon which would engage and hold the yarn and cause abreakage of some strands of yarn if the sheet .of warp should be allowedto contact these rough bars.

It is thus seen that I have provided a, simple framework havingstrumming means associated therewith which can be quickly placed inassociation with a beamer and which will strum the warp threads from thelower side and will not in any way interfere with the operation of thebeamer, and which can be easily removed to gain access to any portion ofthe beamer.

In the drawings and specification, there has been set forth a preferredembodiment of the invention, and although specific terms are employed,they are used in a generic and descriptive sense only, and not forpurposes of limitation, the scope of the invention being defined in theclaims.

I claim:

1. Apparatus for strumming a sheet of Warp as it travels to a warp beamin a beamer comprising a framework disposed below the sheet of warp, andhaving a plurality of members mounted for pivotal movement intermediatetheir ends, and having at each end thereof upwardly projecting resilientfingers for penetrating the warp, means driven by the beamer forimparting oscillatory movement to said members in a horizontal plane toprogressively engage various ones of the warp threads for imparting astrumming action thereto.

2. In strumming apparatus adapted to be associated with the beamer, aframework disposed adjacent the beamer and below a sheet of warptraveling to the beamer, a plurality of members pivotally mountedtherein on the frame and below the Warp and having uprising fingers ateach end thereof, means driven by the beamer and pivotally connected tosaid members for oscillating said members to move said fingerstransversally of the warp for strumming the warp.

3. Apparatus for strumming a sheet of warp as it travels to a warp beamin a beamer comprising a framework disposed below the sheet of warp, andhaving a plurality of members mounted for pivotal movement intermediatetheir ends, and having on at least one end thereof upwardly projectingresilient fingers for penetrating the warp, means driven by the beamerfor imparting oscillatory movement to said members in a horizontal planeto progressively engage various ones of the warp threads for imparting astrumming action thereto.
